FOOT-CONTROL ACCELERATOR FOB MOTOR-C. KRS.

To all whom 'it may concern:

Be it knownl that I, Geenen WuLoiiD, a citizen of the United States,residin at Excelsior Sap/finge, in the county of lay and State of.issoiii-i, have invented certain new and useful Improvements inFoot-Control Accelerators for' Motor-Cars, of which the following is aspecification.

This invention relates to foot accelerators for motor cars andmoreespecially to devices designed for attachment to Ford cars und thelike','"w-liereby vthe tootmay be utilized for operating the throttle ofthe carbureter to increase the supply of gas to the engine, and myobject is to produce a simple, strong, durable `and cheap acceleratorattachment which can be easily; quickly and vcheaply applied to a carand which 'willlperforni its function etliciently and withoiitinterfering withthe voperation of the throttle by the customary handcontrol mechanism. 4

With this ob]ect in` view, the invention consists in certain novel and.peculiar feai tures of construction and .organization as hereinafterdescribedl and claimed; and in order that it may be fully understoodreference is to be had to the accompanying drawing., in which-d I Figure1y5 is a. top plan view of a lportion of a car equipped with a footaccelerator uttac'lment embodying my invention.
